Several predictors of a mother's perception of her child's weight (MPCW) when the child is overweigh-obese (OW-OB) were identified. Participants: 2,842 mothers and children who reside in Mexico's northeastern region, 951 mothers had an OW-OB child. The MPCW was evaluated for words (PW) and images (PI). PW, 63.71%25 and 74.9%25 of the mothers with an OW-OB child, did not perceive the child's weight adequately and PI, 27%25 and 10.99%25. Through Logistic Regression Analysis, a model for PW was X2 = 152.05, gl = 9, p = 0.001, 21.5%25 explained variance; and for PI X2 = 192.35, gl = 9, p = 0.001, 31.9%25 explained variance. The child's age, a doctor's report that the child had OW, were some variables that contributed to the models. We concluded that mothers with OW-OB children do not adequately perceive this situation. We emphasize the importance of reporting of a child's OW-OB condition.
